Near-Surface BOP Drilling System

摘要

The idea of using a surface BOP located on the deck has received much attention in recent years. Despite the numerous benefits provided by a surface BOP drilling system in comparison with the conventional subsea BOP system, its safety remains a concern. This paper presents a hybrid, freestanding "near-surface" BOP drilling system that combines the better features of the surface and subsea BOP configurations.rnThe near-surface BOP drilling system is described together with the structural analysis and operational assessments that have been performed to demonstrate its feasibility.
